Question

вычислите:
$24 frac{2}{39} - 6 frac{5}{13}$
$14 frac{1}{12} - 1 frac{1}{18}$
$13 frac{1}{18} - 10 frac{1}{12}$
​

Answer 1

$24 frac{2}{39} - 6 frac{5}{13} = 23 frac{41}{39} - 6 frac{15}{39} = \ = 17 frac{26}{39} = 17 frac{2}{3}$

°

$14 frac{1}{12} - 1 frac{1}{18} = 14 frac{3}{36} - 1 frac{2}{36} = 13 frac{1}{36}$

°

$13 frac{1}{18} - 10 frac{1}{12} = 12 frac{38}{36} - 10 frac{3}{36} = \ = 2 frac{35}{36}$
